CROSS REFERENCE TO RELATED APPLICATIONS

This is a 35 U.S.C. 371 national phase application of International patent application, Ser. No. PCT/EP02/10534, filed Sep. 19, 2002, which is a continuation-in-part of U.S. patent application, Ser. No. 09/962,162, filed Sep. 26, 2001, now abandoned.

The present invention relates to aminoindazole derivatives active as kinase inhibitors and, more in particular, it relates to 3-amino-indazole derivatives, to a process for their preparation, to pharmaceutical compositions comprising them and to their use as therapeutic agents, particularly in the treatment of diseases linked to disregulated protein kinases.

The malfunctioning of protein kinases (PKs) is the hallmark of numerous diseases. A large share of the oncogenes and proto-oncogenes involved in human cancers code for PKs. The enhanced activities of PKs are also implicated in many non-malignant diseases, such as benign prostate hyperplasia, familial adenomatosis, polyposis, neuro-fibromatosis, psoriasis, vascular smooth cell proliferation associated with atherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis and post-surgical stenosis and restenosis.

PKs are also implicated in inflammatory conditions and in the multiplication of viruses and parasites. PKs may also play a major role in the pathogenesis and development of neurodegenerative disorders.

For a general reference to PKs malfunctioning or disregulation see, for instance, Current Opinion in Chemical Biology 1999, 3, 459-465.

It is an object of the invention to provide compounds which are useful in therapy as agents against a host of diseases caused by and/or associated to a disregulated protein kinase activity.

It is another object to provide compounds which are endowed with multiple protein kinase inhibiting activity.

The present inventors have now discovered that some 3-aminoindazole derivatives, hereinafter shortly referred to as indazole derivatives or indazoles, are endowed with multiple protein kinase inhibiting activity and are thus useful in therapy in the treatment of diseases associated with disregulated protein kinases.

More specifically, the indazoles of this invention are useful in the treatment of a variety of cancers including, but not limited to: carcinoma such as bladder, breast, colon, kidney, liver, lung, including small cell lung cancer, esophagus, gall-bladder, ovary, pancreas, stomach, cervix, thyroid, prostate, and skin, including squamous cell carcinoma; hematopoietic tumors of lymphoid lineage, including leukemia, acute lymphocitic leukemia, acute lymphoblastic leukemia, B-cell lymphoma, T-cell-lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, hairy cell lymphoma and Burkett's lymphoma; hematopoietic tumors of myeloid lineage, including acute and chronic myelogenous leukemias, myelodysplastic syndrome and promyelocytic leukemia; tumors of mesenchymal origin, including fibrosarcoma and rhabdomyosarcoma; tumors of the central and peripheral nervous system, including astrocytoma, neuroblastoma, glioma and schwannomas; other tumors, including melanoma, seminoma, teratocarcinoma, osteosarcoma, xeroderma pigmentosum, keratoxanthoma, thyroid follicular cancer and Kaposi's sarcoma.

Due to the key role of PKs in the regulation of cellular proliferation, these indazoles are also useful in the treatment of a variety of cell proliferative disorders such as, for instance, benign prostate hyperplasia, familial adenomatosis, polyposis, neuro-fibromatosis, psoriasis, vascular smooth cell proliferation associated with atherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis and post-surgical stenosis and restenosis.

The compounds of the invention can be useful in the treatment of Alzheimer's disease, as suggested by the fact that cdk5 is involved in the phosphorylation of tau protein (J. Biochem., 117, 741-749, 1995).

The compounds of this invention, as modulators of apoptosis, may also be useful in the treatment of cancer, viral infections, prevention of AIDS development in HIV-infected individuals, autoimmune diseases and neurodegenerative disorders.

The compounds of this invention may be useful in inhibiting tumor angiogenesis and metastasis.

The compounds of the invention are useful as cyclin dependent kinase (cdk) inhibitors and also as inhibitors of other protein kinases such as, for instance, protein kinase C in different isoforms, Met, PAK-4, PAK-5, ZC-1, STLK-2, DDR-2, Aurora 1, Aurora 2, Bub-1, PLK, Chk1, Chk2, HER2, raf1, MEK1, MAPK, EGF-R, PDGF-R, FGF-R, IGF-R, VEGF-R, PI3K, weel kinase, Src, Abl, Akt, ILK, MK-2, IKK-2, Cdc7, Nek, and thus be effective in the treatment of diseases associated with other protein kinases.

Stirring is carried out for a suitable time varying from about 1 hour to about 4 hours.

According to step c) of the process, the compound of formula (V) is converted into the corresponding hydroxy derivative through reaction with a suitable ether cleaving agent such as, for instance, pyridinium hydrochloride salt, iodotrimethylsilane or boron tribromide. The reaction may be carried out in neat pyridinium chloride or, with the other reagents, in dichloromethane or chloroform.

Preferably, neat pyridinium chloride is used.

In this respect, the mixture of pyridinium chloride and of the compound of formula (V) is brought to a suitable temperature of from about 180° C. to about 200° C. whereas stirring is carried out for a time varying from about 1 hour to about 3 hours.

According to step d) of the process, the compound of formula (VI) is reacted with a silyl derivative, preferably tert-butyl-dimethyl-silyl chloride (TBDMSCl), so as to get the corresponding silyl ether derivative. The reaction may be carried out in presence of a suitable base such as, for instance, 1,5-diazabiciclo[4.3.0]non-5-ene (DBN) or, more preferably, 1,8-diazabiciclo[5.4.0]undec-7-ene (DBU).

In this respect, tert-butyl-dimethyl-silyl chloride (TBDMSCl) is added to a solution of the compound of formula (VI). The reaction may be carried out in a variety of solvents such as dichloromethane, acetonitrile, dimethylformamide and the like; dichloromethane being preferred. The temperature may vary from about 20° to about 40° C. whilst stirring is maintained for a time of about 1 hour to 4 hours.

According to step e) of the process, the indazole derivative of formula (VII) thus obtained is either protected at the indazole nitrogen atom or, alternatively, is supported onto a suitable polymeric resin.

The reaction of protection may be carried out according to conventional methods well known in the art, for instance by using suitable nitrogen protecting groups such as, for instance, tert-butoxy-carbonyl (BOC) group.

At this same position, in the alternative, the indazole of formula (VII) may be conveniently anchored to an inert polymeric support such as, for instance, the 2-chloro-trityl chloride resin, the trityl chloride resin, the p-nitrophenyl carbonate Wang resin or the bromo-4-methoxyphenyl)methyl polystyrene, which are all conventionally known in this field.

Clearly, this same option is particularly advantageous for preparing the compounds of formula (I) under solid-phase-synthesis (SPS) conditions, which are typically adopted when preparing libraries of compounds according to combinatorial chemistry techniques, for instance as reported below.

The reaction with the resin is carried out in the presence of a slight excess of a suitable base, for instance an amine, e.g. diisopropylethylamine (DIPEA), triethylamine (TEA), 1,8-diazabiciclo[5.4.0]undec-7-ene (DBU) or 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diaza-phosphorine, in a suitable solvent, for instance dichloromethane, chloroform, tetrahydrofuran, dimethylformamide, dimethylacetamide and the like.

Preferably, the reaction is carried out in dichloromethane at a temperature of about 20° C.

The reaction may be performed by adding to a suspension of the resin, the base and the compound of formula (VII), and by stirring at a temperature of about 20° C. for a suitable time, for instance up to 24 hours.

According to step f) of the process, the derivative of formula (VIII) is treated with hydrazine monohydrate so as to cleave the phthalimido group.

The reaction is preferably carried out by using a large excess, for instance up to 10 equivalents, of hydrazine hydrate or monohydrate, in the presence of suitable solvents such as, for instance, halogenated hydrocarbons, lower alcohols and admixtures thereof.

Preferred solvents are dichloromethane, ethanol and admixtures thereof.

The reaction may be carried out by adding hydrazine to a solution of the compound of formula (VIII) and by stirring for a suitable time at the temperature ranging from about 20° to about 45° C. Preferably, the reaction mixture is maintained under stirring at about 40° C. for about 16 hours.

According to any one of steps g.1) or g.2) of the process, the amino derivative of formula (IX) is reacted with a suitable reagent of formula from (X) to (XIV), or with a compound of formula (XVII), according to well-known methods.

Typically, the compound of formula (IX) may be reacted with: a compound of formula (X) so as to get the corresponding —NHR′ derivative wherein R′ is as above defined; a compound of formula (XI) to get the corresponding —NHCOR′ acyl derivative; a compound of formula (XII) to get the corresponding —NHCONHR′ ureido derivative; a compound of formula (XIII) to get the corresponding —NHSO₂R′ derivative; a compound of formula (XIV) to get the corresponding —NHCOOR′ derivative. Alternatively, the compound of formula (IX) may be reacted with a compound of formula R′R″NH (XVII), in the presence of 4-nitrophenyl chloroformate to get the corresponding ureido —NHCONR′R″ derivative.

Any one of the above reactions is carried out according to conventional methods normally used in the preparation of functionalized amino derivatives, by starting from the corresponding amine.

Preferably, within the compounds of formula (X), z represents a suitable leaving group, for instance, iodine bromine or boronic acid; within the compounds of formula (XI) (XIII) or (XIV), Z represents a halogen atom and, even more preferably, a chlorine atom.

In addition to the above, it is clear to the skilled man that, whenever desired, any of the above compounds of formula (XV) thus prepared and wherein R represents a group —NHR′ or —NHCONHR′ may be further converted into the corresponding derivative having R as a —NR′R″ or —NHCONR′R″ group, respectively.

Also these reactions are performed according to conventional methods by reacting the proper intermediate compound of formula (XV) with a suitable derivative of formula (XVI).

In this respect, the compound of formula (IX) is dissolved in a suitable solvent such as dichloromethane, dimethylformamide, tetrahydrofuran, dioxane or the like, and a suitable base such as triethylamine, diisopropylethylamine, sodium carbonate or the like is added. The compound of general formula (XI), (XIII) or (XIV) is then added and the mixture stirred for a time of about 2 hours to about 15 hours, at a temperature ranging from about 20° C. to about 80° C. When using an isocyanate of general formula (XII), the reaction conditions are the same as above except that the base may not be required. In all of these reactions, a suitable catalyst such as dimethylamino pyridine may be optionally used.

Substantially analogous procedures may be applied when the compound of formula (XII) is reacted with a compound of formula (X) to give the corresponding functionalized amino derivative of formula (XIV), according to well known methods.

As an example, the compound of formula (IX) may be reacted with a derivative of formula (X) wherein Z is halogen, for instance iodine or bromine, and R′ is an arylalkyl group such as, for instance, a benzyl group, by working according to conventional methods.

On the other side, the compound of formula (IX) may be reacted with a derivative of formula (X) wherein Z is a bromine atom and R′ is an aryl group, in presence of a palladium catalyst such as, for instance, tris(dibenzylideneacetone)dipalladium, palladium acetate or 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium, by adding a suitable base, for instance potassium tert-butoxide, cesium carbonate or the like, and a palladium ligand such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, tri-o-tolylphosphine, tri-n-butylphosphine, tri-t-butylphosphine and the like, so as to obtain the corresponding derivative of formula (XV).

In this respect, the compound of formula (IX) is suspended in a suitable anhydrous solvent such as toluene, N-methyl-2-pyrrolidone, dimethoxyethane, dioxane and the like, and the compound of formula (X), the catalyst, the base and the ligand are added therein. The suspension is then brought to a suitable temperature varying from about 50° C. to about 100° C. whereas stirring is maintained for a time of about 8 hours to 5 hours. The reaction is carried out under inert atmosphere.

According to step h) of the process, the compound of formula (XV) is then reacted with tetrabutylammonium fluoride so as to get the corresponding hydroxy derivative of formula (XVIII). The compound (XV) may be thus suspended in an anhydrous solvent such as dioxane, tetrahydrofuran or the like, and the solution of tetrabutylammoniun fluoride in the suitable solvent is added. The solution is stirred for about 2 hours to about 16 hours, at a temperature ranging from about 20° C. to about 50° C.

The product of formula (XVIII) thus obtained may be further reacted according to step i) of the process, with a suitable derivative of formula (XIX).

More in particular, the reaction with a compound of formula (XIX) wherein Z is a halogen atom such as bromine or chlorine or a suitable leaving group, is carried out in the presence of a base such as, for instance, sodium hydroxide, sodium hydride, 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diaza-phosphorine or more preferably cesium carbonate, so as to get the corresponding ether derivative of formula (XX).

In this respect, the compound of formula (XVIII) is suspended in a suitable solvent such as dimethylacetamide, tetrahydrofuran, dioxane or more preferably dimethylformamide, and the base is added.

The mixture is stirred for about 5 hours to about 36 hours at a temperature ranging from about 20° C. to about 80° C. Alternatively, these same compounds of formula (XX) may be obtained by reacting the derivative of formula (XVIII) with a compound of formula (XIX) wherein Z is hydroxy, under Mitsunobu operative conditions, e.g. in the presence of triphenylphosphine and diisopropyl azodicarboxylate.

In this respect, triphenylphosphine, diisopropyl azodicarboxylate and the compound of general formula (XIX) are dissolved in a suitable solvent such as tetrahydrofuran, dioxane or the like, and the solution is transferred into the mixture of the compound of formula (XVIII) being dissolved in a suitable solvent such as tetrahydrofuran, dioxane or the like, in the presence of a suitable base such as triethylamine or diisopropylethylamine. The mixture is stirred for a time varying from about 2 hours to about 15 hours, at a temperature ranging from 0° C. to 20° C.

Finally, according to step j) of the process, the compound of formula (XX) is deprotected at the indazole nitrogen atom by working, according to conventional method, in acidic conditions. The compound of formula (XX) is suspended in a suitable solvent such as methyl alcohol, ethyl alcohol or the like, and a concentrated solution of hydrochloric acid is added. The mixture is stirred for a suitable time of about 5 hours to about 15 hours at a temperature ranging from about 20° C. to about 40° C.; preferably at about 20° C. Alternatively, this same intermediate compound of formula (XX) is cleaved from the resin to which it is supported.

Resin cleavage may be carried out, for instance, in the presence of trifluoroacetic acid so as to yield the desired compound of formula (I). The resin is suspended in a solution of 5-95% of trifluoroacetic acid in dichloromethane and the mixture is stirred at about 20° C. for a time varying from about 5 minutes to about 3 hours.

From all of the above, it is clear to the skilled man that the compounds of formula (I) wherein R₁ and m are as above defined and R is a phthalimido group of formula (II), and the pharmaceutically acceptable salts thereof, may be prepared according to an analogous process by reacting the compound of formula (VIII) as per steps h), i) and j) of the process, so as to get the desired derivative of formula (I) bearing a phthalimido group (II) in place of the R group.

Preferably, when preparing the compounds of formula (I) wherein R is a sulfonamido(—NHSO₂R′) group, the above synthetic pathway can be conveniently modified by changing the order of the deprotection steps.

More in particular, the compounds of formula (I) wherein R is a —NHSO₂R′ group may be-preferably prepared by reacting the intermediate derivatives of formula (VIII), being obtained according to step (e) of the process, with tetrabutylammonium fluoride as per step (h) of the process, so as to obtain the compounds of formula (XVIII) wherein R is a phthalimido group.

The thus obtained compounds of formula (XVIII) are then reacted with a derivative of formula (XIX) according to step (i) of the process, so as to get the compounds of formula (XX) wherein R is a phthalimido group.

The above compounds of formula (XX) are then reacted with hydrazine monohydrate, according to step (f) of the process, so as to obtain the compounds of formula (XX) wherein R is —NH₂.

Finally, the above compounds of formula (XX) are then reacted with a suitable derivative of formula (XIII), as per step (g.1) of the process, so as to get the corresponding sulphonamido derivatives of formula (XX) wherein R represents the given —NHSO₂R′ group, which are further deprotected or cleaved from the resin according to step (j) of the process.

When preparing the compounds of formula (I) according to any variant of the process, which are all to be intended as within the scope of the present invention, optional functional groups within both the starting materials, the reagents or the intermediates thereof, which could give rise to unwanted side reactions, need to be properly protected according to conventional techniques. Likewise, the conversion of these latter into the free deprotected compounds may be carried out according to known procedures.

Pharmaceutically acceptable salts of the compounds of formula (I) or, alternatively, their free compounds from the salts thereof, my be all obtained according to conventional methods.

The compounds of formula (III) are known or easily prepared according to known methods. As an example, 2-amino-4-methoxy-benzonitrile may be prepared by working as described in EP-A-257583 in the name of Shionogi & Co; 2-amino-5-benzyloxy-benzonitrile may be prepared as described in J. Heterocycl. Chem. (1972), 9(4), 759-73.

If not commercially available per se, all of the compounds of formula (X), (XI), (XII), (XIII), (XIV), (XVI), (XVII) and (XIX) are known or easily prepared according to well-known methods.

Likewise, any reagent of the present process comprising the silyl derivative (R^(iv))₃SiZ as well as the polymeric resin are commercially available or readily preparable from commercially available sources.

Pharmacology

The compounds of formula (I) are active as protein kinase inhibitors and are therefore useful, for instance, to restrict the unregulated proliferation of tumor cells.

In therapy, they may be used in the treatment of various tumors such as, for instance, carcinomas, e.g. mammary carcinoma, lung carcinoma, bladder carcinoma, colon carcinoma, ovary and endometrial tumors, sarcomas, e.g. soft tissue and bone sarcomas, and the hematological malignancies such as, e.g., leukemias.

In addition, the compounds of formula (I) are also useful in the treatment of other cell proliferative disorders such as psoriasis, vascular smooth cell proliferation associated with atherosclerosis and post-surgical stenosis and restenosis and in the treatment of Alzheimer's disease.

The inhibiting activity of putative cdk/cyclin inhibitors and the potency of selected compounds was determined through a method of assay based on the use of the SPA technology (Amersham Pharmacia Biotech).

The assay consists of the transfer of radioactivity labelled phosphate moiety by the kinase to a biotinylated substrate. The resulting 33P-labelled biotinylated product is allowed to bind to streptavidin-coated SPA beads (biotin capacity 130 pmol/mg), and light emitted was measured in a scintillation counter.

Inhibition Assay of cdk2/Cyclin A Activity

Kinase reaction: 4 μM in house biotinylated histone H1 (Sigma # H-5505) substrate, 10 μM ATP (0.1 microCi p³³γ-ATP), 4.2 ng Cyclin A/CDK2 complex, inhibitor in a final volume of 30 μl buffer (TRIS HCl 10 mM pH 7.5, MgCl₂ 10 mM, DTT 7.5 mM+0.2 mg/ml BSA) were added to each well of a 96 U bottom. After 30 min at r.t. incubation, reaction was stopped by 100 μl PBS+32 mM EDTA+0.1% Triton X-100+500 μM ATP, containing 1 mg SPA beads. Then a volume of 110 μl is transferred to Optiplate.

After 20 min. incubation for substrate capture, 100 μl 5M CsCl were added to allow statification of beads to the top of the plate and let stand 4 hours before radioactivity counting in the Top-Count instrument

IC50 determination: inhibitors were tested at different concentrations ranging from 0.0015 to 10 μM. Experimental data were analyzed by the computer program GraphPad Prizm using the four parameter logistic equation: y=bottom+(top−bottom)/(1+10^((logIC50−x)*slope)) where x is the logarithm of the inhibitor concentration, y is the response; y starts at bottom and goes to top with a sigmoid shape. Ki Calculation:

Experimental method: Reaction was carried out in buffer (10 mM Tris, pH 7.5, 10 mM MgCl₂, 0.2 mg/ml BSA, 7.5 mM DTT) containing 3.7 nM enzyme, histone and ATP (constant ratio of cold/labeled ATP 1/3000). Reaction was stopped with EDTA and the substrate captured on phosphomembrane (Multiscreen 96 well plates from Millipore). After extensive washing, the multiscreen plates are read on a top counter. Control (time zero) for each ATP and histone concentrations was measured.

Experimental design: Reaction velocities are measured at different four ATP, substrate (histone) and inhibitor concentrations. An 80-point concentration matrix was designed around the respective ATP and substrate Km values, and the inhibitor IC50 values (0.3, 1, 3, 9 fold the Km or IC50 values). A preliminary time course experiment in the absence of inhibitor and at the different ATP and substrate concentrations allow the selection of a single endpoint time (10 min) in the linear range of the reaction for the Ki determination experiment.

Kinetic parameter estimates: Kinetic parameters were estimated by simultaneous nonlinear least-square regression using [Eq. 1] (competitive inhibitor respect to ATP, random mechanism) using the complete data set (80 points):

$\begin{matrix} {v = \frac{{Vm} \cdot A \cdot B}{\begin{matrix} {{\alpha \cdot {Ka} \cdot {Kb}} + {\alpha \cdot {Ka} \cdot B} +} \\ {{a \cdot {Kb} \cdot A} + {A \cdot B} + {\alpha \cdot \frac{Ka}{Ki} \cdot I \cdot \left( {{Kb} + \frac{B}{\beta}} \right)}} \end{matrix}}} & \left\lbrack {{Eq}.\mspace{14mu} 1} \right\rbrack \end{matrix}$ where A=[ATP], B=[Substrate], I=[inhibitor], Vm=maximum velocity, Ka, Kb, Ki the dissociation constants of ATP, substrate and inhibitor respectively. α and β the cooperativity factor between substrate and ATP binding and substrate and inhibitor binding respectively.

As formerly indicated, several compounds of formula (I) of the invention have been synthesized in parallel, according to combinatorial chemistry techniques.

In this respect, some compounds thus prepared have been conveniently and unambiguously identified, as per the coding system of tables from 1× to XVI, together with HPLC retention time (methods 1 to 3) and mass.

Each code, which identifies a single specific compound of formula (I), consists of three units A-M-B.

A represents any substituent R₁-[see formula (I)] and is attached to the rest of the indazole moiety through the oxygen atom so as to get indazole derivatives being substituted in position 5 (A-M1-B) or in position 6 (A-M2-B); each A radical (substituent) is represented in the following table VII.

Together with the —NH— group in position 3 of the indazole moiety to which it is attached, B—NH— represents the R group of formula (I); each B radical (substituent) is represented in the following table VIII.

M refers to the central core of the divalent 3-amino-indazole moiety having the —O— group in position 5 or 6 and is substituted by groups A and B.

In particular, M may vary from M1 or M2 as per the formulae below, each identifying a compound being substituted by A-O— groups in position 5 (M1) or in position 6 (M2)

For ease of reference, each A or B groups of tables VII and VIII has been identified with the proper chemical formula also indicating the point of attachment with the rest of the molecule M.

Just as an example, the compound A21-M1-B10 of table XI (see example 11, entry 429) represents an indazole M1 being substituted in position 5 (through the oxygen atom) by the group A21 and in position 3 (through the —NH— group) by the group B10; likewise, the compound A10-M2-B70 of table XII (see example 12, entry 281) represents an indazole M2 being substituted in position 6 (through the oxygen atom) by the group A10 and in position 3 (through the —NH— group) by the group B70:

EXAMPLE 12 1-(6-Benzyloxy-1H-indazol-3-yl)-3-butyl-urea

500 mg of Novabiochem trityl resin (declared substitution 1.27 mmol/g, 0.64 mmol) were suspended in dichloromethane and 374 mg of 2-[6-(tert-butyl-dimethyl-silanyloxy)-1H-indazol-3-yl]-isoindole-1,3-dione (0.9 mmol) and 367 μl of 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (1.3 mmol) were added. The suspension was stirred for 16 hours and then the resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane again. The resin was then dried under vacuum.

The identity of the resin and the yield of the loading step were checked by cleavage of the loaded product:

40 mg of resin were suspended in 1 ml of dichloromethane and 150 μl trifluoroacetic acid were added. After 2 hours the resin was drained and washed twice with 1 ml of dichloromethane; the collected solutions were dried and 13.8 mg of titled compound recovered. Calculated loading 0.85 mmol/g, HPLC r.t. Method 1: 7.64 [M+H]+=394.

The resin obtained from the first step (300 mg, ˜0.25 mmol) was suspended in 5 ml of a mixture of dichloromethane and methanol 1:1 and 400 μl of hydrazine monohydrate were added. The suspension was heated to 45° C. Heating and stirring were continued overnight, and then the mixture was cooled down to room temperature. The resin was filtered and washed with a mixture of methanol and water 1:1, methanol, dimethylformamide, and methanol again, before drying under vacuum.

The identity of the resin was checked by cleavage. The reaction was performed as described above.

Cleaved compound: 6-{[tert-butyl(dimethyl)silyl]oxy}-1H-indazol-3-amine: HPLC r.t. Method 1: 5.99 [M+H]+=264; [M-H]−=262

A sample of the resin obtained from the second step (100 mg, 0.08 mmol) was suspended in 2 ml of dimethylformamide; N-butyl isocyanate (28 μl ˜5 eq) was added. The suspension was heated to 50° C. Stirring and heating was maintained for 60 hours, then the suspension was cooled down to room temperature. The resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane, before drying under vacuum.

The resin obtained from the third step (100 mg, 0.08 mmol) was suspended in 3 ml of tetrahydrofuran anhydrous and 120 μl of a solution 1 M of tetrabutylammonium fluoride in tetrahydrofuran (˜1.5 eq) were added. The suspension was stirred overnight then the resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane.

Cleaved compound: 1-butyl-3-(6-hydroxy-1H-indazol-3-yl)-urea; HPLC Method 1 r.t. 3.87 [M+H]+=249 [M−H]−=247.

The resin obtained from the fourth step (100 mg, 0.08 mmol) were suspended in 3 ml of 1-methyl-2-pyrrolidinone, then 43 μl of 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (˜1.5 eq) and 57 μl of benzyl bromide (˜6 eq) were added. The suspension was stirred for 16 hours. The resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane.

100 mg of dry resin were suspended in 3 ml of dichloromethane and 450 μl trifluoroacetic acid were added. After 2 hours the resin was drained and washed twice with 3 ml of dichloromethane; the collected solutions were dried; the title compound recovered

EXAMPLE 16 N-{[5-(benzyloxy)pentyl]oxy}-1H-indazol-3-yl)-N′-isopropylurea

500 mg of Novabiochem trityl resin (declared substitution 1.27 mmol/g, 0.64 mmol) were suspended in dichloromethane and 374 mg of 2-[5-(tert-butyl-dimethyl-silanyloxy)-1H-indazol-3-yl]-isoindole-1,3-dione (0.9 mmol) and 367 μl of 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-,1,3,2-diazaphosphorine (1.3 mmol) were added. The suspension was stirred for 16 hours and then the resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane again. The resin was then dried under vacuum.

The identity of the resin and the yield of the loading step were checked by cleavage of the loaded product:

40 mg of resin were suspended in 1 ml of dichloromethane and 150° μl trifluoroacetic acid were added. After 2 hours the resin was drained and washed twice with 1 ml of dichloromethane; the collected solutions were dried and 13.8 mg of titled compound recovered. Calculated loading 0.85 mmol/g, HPLC r.t. Method 1: 7.64 [M+H]+=394.

The resin obtained from the first step (500 mg, ˜0.425 mmol) was suspended in 5 ml of a mixture of dichloromethane and methanol 1:1 and 500 μl of hydrazine monohydrate were added. The suspension was heated to 45° C. Heating and stirring were continued overnight, and then the mixture was cooled down to room temperature. The resin was filtered and washed with a mixture of methanol and water 1:1, methanol, dimethylformamide, and methanol again before drying under vacuum.

The identity of the resin was checked by cleavage. The reaction was performed as described above.

6-{[tert-butyl(dimethyl)silyl]oxy}-1H-indazol-3-amine HPLC r.t. Method 1: 5.99 [M+H]+=264 [M−H]−=262

A sample of the resin obtained from the second step (100 mg, 0.08 mmol) was suspended in 2 ml of dimethylformamide; isopropyl isocyanate (39 μl, 0.4 mmol, ˜5 eq) was added. The suspension was heated to 50° C. Stirring and heating was maintained for 60 hours, then the suspension was cooled down to room temperature. The resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane, before drying under vacuum.

The resin obtained from the third step (100 mg, ˜0.08 mmol) was suspended in 3 ml of tetrahydrofuran anhydrous and 120 μl of a solution 1 M of tetrabutylammonium fluoride in tetrahydrofuran (˜1.5 eq) were added. The suspension was stirred overnight then the resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane, before drying under vacuum.

The resin obtained from the fourth step (100 mg, ˜0.08 mmol) was suspended in 1 ml of tetrahydrofuran anhydrous. In a round bottom flask, 209 mg of triphenylphosphine (0.8 mmol, ˜10 eq) were dissolved in 2 ml of tetrahydrofuran anhydrous, then 157 μl of diisopropyl azodicarboxylate (0.8 mmol, ˜10 eq) and 230 μl of 5-benzyloxy-1-pentanol (1.2 mmol, ˜15 eq) were gently added at 0° C. The solution was left shaking 2 h, then transferred into the suspension of the resin.

The suspension was stirred overnight then the resin was filtered and washed with dichloromethane, methanol, dimethylformamide, methanol and dichloromethane.

The procedure is repeated twice.

100 mg of dry resin were suspended in 3 ml of dichloromethane and 450 μl trifluoroacetic acid were added. After 2 hours the resin was drained and washed twice with 3 ml of dichloromethane; the collected solutions were dried and the desired title compound recovered.
